摘要：
Aluminum added to MgO-C refractories reacts with carbon to form Al4C3 during heating. Since it hydrates as the bricks are cooled, it causes the collapse of the refractories during reheating. The defect can be overcome by the use of Al8B4C7. In this paper, the effect and behaviour of Al-B-C system antioxidants added to MgO-C refractories have been investigated.
